Bloomberg.com - Mortgage rates for 30-year U.S. loans fell to a three-month low after a partial government shutdown pushed down yields for the Treasuries that guide consumer debt.

The average rate for a 30-year fixed mortgage dropped to 4.22 percent, the lowest since June 20, from 4.32 percent, Freddie Mac said in a statement today. The average 15-year rate decreased to 3.29 percent from 3.37 percent, according to the McLean, Virginia-based company.
